[public-dns-discuss] Reverse DNS Lookup issues



Hi

We have Reverse DNS Lookup issues for our MX records mxgate01.cyient.com & mxgate02.cyient.com. Need help in fixing the same.

Unable to do a reverse lookup from google servers only.

> 110.76.160.224
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

*** google-public-dns-a.google.com can't find 110.76.160.224: Server failed
> 110.76.168.203
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

*** google-public-dns-a.google.com can't find 110.76.168.203: Server failed
> exit


I have no issues from other DNS servers. Please find the below.
